BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electronic purse having a settlingfunction, suitable for an electronic money system which transferselectric information (electronic money information), i.e., a value(amount of money) corresponding to the amount of money stored in an ICcard, instead of actually transferring that money, and in particular, toan electronic purse which transfers electronic money information (amountof money information) through communication lines such as publictelephone lines.

2. Description of Related Art

Conventionally, in an electronic money system transferring electronicmoney information corresponding to an amount of money, instead of actualmoney, transferring of electronic money information is performed, asdescribed in Japanese Patent Laid-Open (KOKAI) No. 3-92966 for example,in such a manner that each person having an IC card, visits a shop, anautomatic vending machine, or a bank (hereinafter, generally referred toas “shop” for simplicity), and uses a terminal unit installed in eachshop. When each person wishes to receive electronic money information,they must visit a shop having a terminal unit and insert their IC cardinto the terminal unit to receive replenishment of electronic money.

The terminal unit installed in a shop functions to carry outtransactions using input of values of electronic money information.However, to draw the balance from one's account to leave a balance ofnothing, it is necessary to input a value of electronic moneyinformation, which is a troublesome operation.

Further, the terminal unit installed in a shop functions to carry outactive transactions in which a value of electronic money information anda direction of transfer, i.e., indication of receipt or payment, areinputted. However, it is not constructed to be compatible with a passivefunction which works on a transaction partner's designation of a valueof electronic money information and a direction of transfer.

The electronic money system described in Japanese Patent Laid-Open(KOKAI) No. 6-162059 proposes electronic purses which can be connectedthrough a telephone communication means. However, it does not disclosemeans for improving the above-described troublesome operation orinsufficient function.

SUMMARY OF THE INVENTION

An electronic purse in the conventional electronic money system istroublesome in its operation, because many instructing operations arerequired for payment and receipt of electronic money information. Forexample, it is necessary to select and set a direction of transferringelectronic money information from many choices. Even to transfer a givenvalue of electronic money information, as in the case of remittance ofthe entire balance or of a fixed amount, that value must be setexplicitly.

Further, it has been impossible to reconcile a function of transferringelectronic money information in which a transaction partner designates avalue of electronic money and a direction of transaction and a functionof transaction in which a user performs various settings actively forthemselves.

Furthermore, when electronic money information is received and sentthrough public telephone lines, receipt and sending of voice informationis stopped during the receipt and sending of the electronic moneyinformation and a silent state exists, and it is therefore difficult toconfirm that the system is working. Further, transfer of voiceinformation through the telephone communication lines becomesimpossible.

Thus, an object of the present invention is to simplify instructingoperations for transferring electronic money information. To give moredetail, the present invention reduces instructing operations in settinga direction of transferring electronic money information and a value tobe transferred.

Here, the remittance direction switching unit 12, IC card remittancedirection switching unit 13, external switching unit 14, devicediscriminating signal sending member 16, device response detectingmember 18, remittance direction data sending member 20, remittancedirection detecting member 21, and processor 29 are, in fact, functionalmeans constructed by CPU, programs, memory, and the like.

Now, operation of the electronic purse having the above-describedconstruction will be described referring to FIGS. 2-5. FIG. 2 is aflowchart of the processing operation mainly in the processor 29,showing processing from detection of an operation input signal of thetransaction button 23 in the electronic purse shown in FIG. 1 toselective instruction of a direction of transferring electronic moneyinformation (direction of remittance).

When the processor 29 detects the operation input signal of thetransaction button 23 in Step 101, it goes to Step 102 and detectsoutput signals of the IC card detectors 15 a, 15 b. In Step 103, if itis confirmed that only one of the IC cards 1 a, 1 b is connected to theIC card connecting portion 11 a or 11 b, it goes to Step 104, causingthe device discriminating signal sending member 16 to send a sendingdata sequence (1) 17 to the external device connecting terminal 8. Atthis time, as the sending data sequence (1) 17, there is used a datasequence (1) which has been written into the data storage member 22. Adevice connected to the external device connecting terminal 8, the modemunit 5 in this embodiment, replies to this sending data sequence (1) 17.The returned response is received by the device response detectingmember 18. The detection data sequence 19 received by the deviceresponse detecting member 18 is introduced in Step 105, and in the nextStep 106, this detection data sequence 19 is compared with a datasequence (2). At this time, as the data sequence (2), there is used adata sequence (2) which has been written into the data storage member22. In the comparison of Step 106, if it is confirmed that the detectiondata sequence 19 is the same sequence as the data sequence (2), it goesto Step 107, judging that the modem unit 5 is connected to the main body2 of the electronic purse. Thereafter, in Step 108, the modem unit 5 isinitialized as required, by sending a data sequence (4) which has beenwritten into the data storage member 22.

In the comparison of the above-described Step 106, in the case that thedetected detection data sequence 19 is different from the data sequence(2) written into the data storage member 22, it goes to Step 109,comparing the detection data sequence 19 with the next data sequence (3)written into the data storage member 22. In the present embodiment, thedata sequence (3) is the data sequence used by the main body 2 of theelectronic purse for response when it receives the same data sequence asthe data sequence (1) written into the data storage member 22, via theexternal device connecting terminal 8. Thus, if the detection datasequence 19 is the same as the data sequence (3), it goes to Step 110,recognizing that another usable main body of the electronic purse isconnected directly to the external device connecting terminal 8.

When the processor 29 recognizes that a usable device is connected tothe external device connecting terminal 8, it goes to Step 111,displaying a selection menu (2) screen on the display unit 28 forallowing selective instruction of a direction of transferring electronicmoney information, and entry into remittance (transfer of electronicmoney information) control processing in relation to the externaldevice.

In the case that, in Step 103 and Step 112, two IC cards 1 a, 1 bconnected to the two IC card connecting portions 11 a, 11 b aredetected, it goes to Step 113, and in the present embodiment, aselection menu (1) screen is always displayed, which allows selectiveinstruction of a direction of transferring electronic money informationbetween the two IC cards 1 a, 1 b, regardless of the fact that anexternal device is connected to the external device connection terminal8, and the process flow enters remittance (transfer of electronic moneyinformation) control processing between the IC cards.

Next, these selection menu screens will be described referring to FIGS.3 and 4. FIG. 3 is the selection menu (1) screen in the case that two ICcards 1 a, 1 b are connected. By operating the selection switch 27 tomove a cursor 30, it is possible to selectively instruct a direction oftransferring electronic money information.

FIG. 4 is the selection menu (2) screen in the case that one IC card 1 a(1 b) is connected. As in the selection menu (1) screen shown in FIG. 3,the selection switch 27 is operated to move the cursor 30 so as toselectively instruct a direction of transferring electronic moneyinformation.

Now, referring to FIG. 5, there will be described processing operationsfor transferring electronic money information in the case that, in theselection menu (2) screen shown in FIG. 4, the selection switch 27 isoperated to selectively instruct a direction of electronic moneyinformation, and a value of electronic money information to betransferred is inputted by the amount of money button 26, and thereafterthe decision button 25 is pushed. The case will also be described wherethe decision button 25 is pushed without operating the amount of moneybutton 26.

FIG. 5 is a flowchart of control processing operations in the processor29, showing from the selection menu (2) screen shown in FIG. 4 forexecution of transfer of electronic money information.

In Step 201, if operation of the decision button 25 is detected, it goesto Step 202, where it is judged if a value of electronic moneyinformation (amount of money to be transferred) has been set byoperation of the amount of money button 26 before the operation of thedecision button 25. In the case that the value of electronic moneyinformation to be transferred has been set, it goes to Step 203, where,first of all, the modem unit 5 is controlled through the external deviceconnecting terminal 8 to make it possible to transfer electronic moneyinformation through the communication line 3. Next, in accordance withthe set value of the transfer direction selected on the selection menu(2) screen shown in FIG. 4, the remittance direction data sending member20 is made to send data indicating the direction of transferringelectronic money information. After that, it goes to Step 204 where theIC card remittance direction switching unit 13, external switching unit14, and remittance direction switching unit 12 are set, and then, toStep 205 where electronic money information is transferred to or fromthe other device through the modem unit 5 and the communication line 3.

On the other hand, in the case that a value of electronic moneyinformation to be transferred (amount of money to be transferred) hasnot been set by operating the amount of money button 26 before theoperation of the decision button 25, the process goes from Step 202 toStep 206, where, first of all, the modem unit 5 is controlled throughthe external device connecting terminal 8 to make it possible totransfer electronic money information through the communication line 3.Next, based on data indicating a direction of remittance, sent from theother device and detected by the remittance direction detecting member21, the transfer direction is detected. Then, it goes to Step 205, wherethe IC card remittance direction switching unit 13, external switchingunit 14, and remittance direction switching unit 12 are set, and furtherto Step 205 to execute transfer of electronic money information to orfrom the other device through the modem unit 5 and the communicationline 3.

In the above-described control processing operation for transferringelectronic money information, in the present embodiment, it is definedthat a device to be connected through the communication line 3 isordinarily connected by a line connecting operation using the telephone4 which is to be connected to the communication line 3 by the lineswitching unit 9. Thereafter, the processor 29 controls the modem unit5, and its control signal 6 controls the line switching unit 9 fortransferring electronic money information. The line switching unit 9connects the modem unit 5 to the communication line 3, while separatingthe telephone 4 from the communication line 3 and connecting it to anoutput circuit of the voice recording-reproducing member 10. The voicerecording-reproducing member 10 outputs a holding tone recorded inadvance.

Next, there will be described the effects of the above-described firstembodiment of the electronic purse according to the present invention,which performs the various operations described above.

In the present embodiment, a direction of transferring electronic moneyinformation between IC cards or in relation to another external devicecan be easily set according to the number of connected IC card(s) 1 andconstruction of a connected device, by simply pushing the transactionbutton 23. At that time, it is automatically judged if the externaldevice can be used or not. As for the selection of functions, selectiveinstructions required from a user are only necessary as minimum ones,thus making the instructing operations easy.

In the present embodiment, when two IC cards 1 a, 1 b are connected, anexternal device connected to the external device connecting terminal 8is not detected, because transfer of electronic money information isinterpreted as one between these two IC cards, thus reducing theavailable choices. However, in an embodiment where a larger number ofchoices are allowed, it may be also detected if an external device isconnected to the external device connecting terminal 8, and when anexternal device is thus connected, all the combinations of transfer ofelectronic money information considering the external device too aredisplayed as choices, so that control of transferring electronic moneyinformation can be performed including that external device. In thatcase, initial data for a transfer direction may be made as a transferbetween the IC cards, which simplifies the instructing operations forselecting a transfer direction.

When it is not necessary to decide a transfer direction, by operatingthe decision button 25 just after operation of the transaction button23, a transfer direction is set in accordance with remittance directiondata given from another device connected externally, and thus theselection operation becomes unnecessary.

Data sequences used for discriminating external devices are stored inthe data sequence storage medium 22 provided separately from theprocessor 29. As a result, by exchanging the data sequence storagemedium 22, data sequences used for discriminating external devices canbe changed easily.

The telephone 4 used for the line connecting operation is separated fromthe communication line 3 during sending and receiving of electronicmoney information, and connected to the voice recording-reproducingmember 10. So that a holding tone is generated. As a result, a user canknow from the sound that the purse is in the middle of the operation ofsending or receiving electronic money information.

Next, referring to FIG. 6, the second embodiment of the electronic purseaccording to the present invention will be described. FIG. 6 is a blockdiagram showing a configuration of the second embodiment of theelectronic purse according to the present invention. The same numeralsare used for components identical to the first embodiment, and repeateddescription is omitted.

In the second embodiment, differing from the first embodiment, there areadded a lump-sum remittance function and lump-sum drawing function, anda lump-sum remittance button 31 and lump-sum drawing button 32 are alsoprovided. The lump-sum remittance function is a function for remitting(transmitting), in a lump-sum, electronic money information stored inthe IC card 1 a (1 b) connected to the IC card connecting portion 11 a(11 b). The lump-sum drawing function is a function for drawing, in alump-sum, all the electronic money information which can be receivedfrom an external device connected through the communication line 3.Control processing for realizing these functions are attained byexecuting programs built into the processor 29.

In the second embodiment, when an operating signal is inputted from thelump-sum remittance button 31, the processor 29 first of all detectsoutput signals of the IC card detectors 15 a, 15 b. In the case that oneIC card 1 a (1 b) is connected to the IC card connecting portions 11 a,11 b, a value of electronic money information stored in this IC card 1 a(1 b) is read. Next, the modem unit 5 connected to the external deviceconnecting terminal 8 is detected. Thereafter, control processing isperformed such that all the values of electronic money information readout are sent to another device connected through the modem unit 5 andthe communication line 3. In this second embodiment, by operating onebutton 31, the processing is performed until sending of the electronicmoney information to the external device is completed.

Next, when an operation signal from the lump-sum button 32 is inputted(the first time), output signals of the IC card detectors 15 a, 15 b aredetected first of all. In the case that one IC card 1 a (1 b) isconnected to the IC card connecting portions 11 a, 11 b, the modem unit5 connected to the external device connecting terminal 8 is detected.Next, by controlling the modem unit 5, information on a value ofelectronic money information which can be obtained from the other devicethrough the communication line 3 is obtained, and displayed on thedisplay unit 28 as balance information. Then, the operation signal fromthis lump-sum drawing button 32 is inputted (the second time), controlprocessing is performed for receiving all the value of the obtainableelectronic money information from the other device through the modemunit 5 and the communication line 3. Without operations based on theinstructions from the other device, this processing can be performeduntil the control processing for receiving the electronic moneyinformation from the other device is completed by operating one button32.

According to the second embodiment, the following effects are obtained.

In the second embodiment, operation of only one button 31 can performremittance of the entire amount of electronic money information storedin the IC card 1 a (1 b), in a lump sum, to other devices, for example,a device installed in a bank. Further, by operating only one button 32,it is possible to receive all the electronic money information which isstored in and can be drawn from another device, for example, a deviceinstalled in a bank.

In describing the second embodiment, there has been shown, as anexample, the control processing for receiving all the electronic moneyinformation which is stored in and can be drawn from another device, byoperating the lump-sum drawing button 32. If necessary, a fixed amountof electronic money information, which has been decided in advance, maybe drawn in a lump sum.

Next, referring to FIG. 7, the third embodiment of the electronic purseaccording to the present invention will be described. FIG. 7 is a blockdiagram showing a configuration of the third embodiment of theelectronic purse according to the present invention. The same numeralsare used for components identical to the first embodiment, and repeateddescription is omitted.

The third embodiment is different from the first embodiment in that anexternal device discriminating switch 33 is provided to discriminateconnection of external devices. This external device discriminatingswitch 33 is provided adjacent to the external device connectingterminal 8, and is constructed so that when a terminal box 34 on theside of the modem unit 5 abuts onto it, the switch is turned on. Theprocessor 29 inputs an output signal of the external devicediscriminating switch 33, and judges if an external device is connectedto the external device connecting terminal 8.

When the terminal box 34 on the side of the modem unit 5 is connected tothe external device connecting terminal 8, the external devicediscriminating switch 33 is operated, and its signal is transferred tothe processor 29. In the present embodiment, this signal from theexternal device discriminating terminal 33 is used for detecting(discriminating) if an external device is connected to the externaldevice connecting terminal 8 or not. Other control processing is thesame as in the first embodiment.

Since the signal from the external discriminating switch 33 is used fordiscriminating if an external device is connected to the external deviceconnecting terminal 8, the control processing is simpler than the firstembodiment. Although, in the present embodiment, the signal fordiscriminating an external device is generated by the external devicediscriminating switch 33, of course, similar effects can be obtained,for example, by employing such a construction that a signal is sent froman external device to a terminal of the external device connectingterminal 8, and the processor 28 receives this signal to detectconnection of the external device.

Next, referring to FIG. 8, the fourth embodiment of the electronic purseaccording to the present invention will be described. FIG. 8 is a blockdiagram showing a configuration of the fourth embodiment of theelectronic purse according to the present invention. The same numeralsare used for components identical to the first embodiment, and repeateddescription is omitted.

This fourth embodiment is different from the first embodiment in thattransfer of electronic money information is performed in parallel withtransfer of voice information. A demultiplexer 35 separates a signalobtained through the communication line 3 into a digital data signal 36and a voice information signal 37, and makes the voice signal 37 branchto the telephone 4. On the other hand, the digital data signal 36 ismade to branch to the main body 2 of the electronic purse through theexternal device connecting terminal 8 for transferring electronic moneyinformation.

In this fourth embodiment, line connecting control through thecommunication line 3 is performed by the telephone 4 as in the firstembodiment. After the connection of the line, transfer of electronicmoney information is performed using the digital data signal 36. At thattime, the telephone 4 sends and receives the voice information signal.Other operations are the same as the first embodiment.

According to such an embodiment, it possible to send and receive thevoice information signal using the telephone 4 while electronic moneyinformation is sent or received, so that guidance of an operation methodof the main body 2 of the electronic purse or other voice informationcan be sent and received or outputted as sound.

As described above, according to the present invention, when an externaldevice is connected to the external device connecting terminal 8, thecontrol processing can be performed so that electronic money isautomatically transferred between an IC card and the external device,thus obtaining easier instructing operations for transferring electronicmoney information.

Further, owing to the lump-sum sending function and lump-sum drawingfunction, a user can transfer electronic money information withoutsetting a value to be transferred and a transfer direction.

Further, whether or not the device is working is easily confirmed bysupplying sound from the telephone during sending and receiving ofelectronic money information.

Still further, electronic money information and voice information aresent and received in a superposed manner by the line superpositionmeans, so that voice information can be transferred during sending andreceiving of electronic money information.

What is claimed is:
 1.
